Title: Controller of internal combustion engine for vehicle
Inventor: MIYAMOTO KATSUHIKO
IPC: F02D41/04
Filed: 2000-06-29
Abstract: PROBLEM TO BE SOLVED: To prevent the combustion of an internal combustion engine from being deteriorated and vehicle start from being sagged by the introduction of an exhaust gas recirculation(EGR) at the time of start of the vehicle. SOLUTION: This controller of the internal combustion engine of a vehicle sets pre-start condition flags when the vehicle stops, and performs the exhaust gas circulation by controlling an EGR valve at a specified opening during idling operation while a brake pedal is depressed under the stopped state (steps S11, S12, S13). When the release of the brake pedal depression is detected in the stopped state, the opening of the EGR valve is reduced while the accelerator pedal is re-depressed (step S14 = Yes) to reduce the amount of EGR. Thus, since the amount of EGR is reduced and the residual EGR in an intake pipe is consumed at the actual pre-start stage, the high output of the internal combustion engine can be provided at start and an excellent accelerating performance of the vehicle can be developed.
